Use the GetPerformanceCounter() function to benchmark how many milliseconds your code takes to execute.
The code has been tested on historical data, with results demonstrating its performance without "repaint" issues.
Future work includes integrating AFL verification into CI/CD pipelines using AmiBroker.exe /CLI and automated parameter stability testing.
// Parameters Length = Param("MA Length", 20, 1, 100, 1); amibroker afl code verified
This is the holy grail. Verified code passes the "Future Leak Test" using StaticVarGet timestamps or the built-in equity() function to ensure signals are not using the close price of the current bar for entry.
Integrate the XRem() function immediately after your logical rules to strip duplicate triggers.
Verified AFL code means the script has been rigorously tested and audited to match real-world market execution. Core Pillars of Verification // Parameters Length = Param("MA Length", 20, 1,
The keyword represents a critical filter between theoretical trading and profitable execution. Unverified code is like a parachute that hasn't been folded by a professional—it might open, or it might kill you.
: Uses variables that can be tuned without breaking the core logic. Anatomy of Verified AFL A reliable snippet usually follows this structural flow:
AmiBroker features a robust built-in Walk-Forward Optimization engine. WFA optimizes parameters on an "In-Sample" segment of historical data, then tests those parameters on a completely unseen "Out-of-Sample" segment. If your AFL code produces profits in-sample but collapses out-of-sample, the code works, but the strategy is overfitted. Monte Carlo Simulations Verified AFL code means the script has been
Scan the code for forbidden phrases referring to the current bar:
SetForeign() returns True only if the ticker exists; otherwise, price arrays are unchanged.
